Subject: [PATCH] gve: Allow pageflips on larger pages
Git-commit: ea5d3455adf1f3d47130604e6d353b23c3ee4a50
Patch-mainline: v5.16-rc1
References: git-fixes
Half pages are just used for small enough packets. This change allows
this to also apply for systems with pages larger than 4 KB.
Fixes: 02b0e0c18ba75 ("gve: Rx Buffer Recycling")
